Overview

Enormous expanses of the Internet are unreachable with standard web search engines. This book provides the key to finding these hidden resources by identifying how to uncover and use invisible web resources. Mapping the invisible Web, when and how to use it, assessing the validity of the information, and the future of Web searching are topics covered in detail. Only 16 percent of Net-based information can be located using a general search engine. The other 84 percent is what is referred to as the invisible Web—made up of information stored in databases. Unlike pages on the visible Web, information in databases is generally inaccessible to the software spiders and crawlers that compile search engine indexes. As Web technology improves, more and more information is being stored in databases that feed into dynamically generated Web pages. The tips provided in this resource will ensure that those databases are exposed and Net-based research will be conducted in the most thorough and effective manner.

    Essential Book For Any Web Searcher

    What a great book, essential reading for anyone who uses the web to find information. It explains, clearly and concisely, what the invisible web is (the 80% of the web that is NOT indexed by search engines) and why that material is 'invisible'. In addition, the book has 19 (!) chapters with descriptions of invisible web resources on topics ranging from health/medicine to news to science. This book should be on every web searcher's desk.

    Ahead of its time

    I think that this book is so good. How good is it you might ask? We'll let me tell you, it is so good, that, like, I know it is so good even before reading it. Can't wait til it's released so that I can see how good it actually is.
